Verified step by step guidance1
Understand that the atomic mass of an element is the weighted average mass of all its naturally occurring isotopes, measured in atomic mass units (u).
Recall or look up the atomic number of titanium (Ti), which is 22, to confirm you are considering the correct element.
Check a reliable periodic table or reference source to find the atomic mass of titanium, which is typically listed below the element symbol.
Compare the given options (32.07 u, 63.55 u, 47.87 u, 55.85 u) to the known atomic mass of titanium from the reference.
Identify the value closest to the known atomic mass of titanium, which is approximately 47.87 u.
